Shoe



Nov. 6, 1945. F'. N. LA CHAPELLE 3 3 3 SHOE Filed Dec. 8, 1941 2 Sheets-Sheet 2 fill the angle for'ned bythe bent upper With the notch outermost. The last is then run through a curVed-needle stitcher to produce the single lineof stitching 40, and the six parts, filler, insole,

lining, counter, upper, and welt are thus securely a gastened all around the shoe tat. the shank and? sole after fiap is returned to its normal position. i

The filler legs 26 provide a simple and conven-- ient means for pegging the outsole to the shanit 48, embedded in the heel, extends through heel base'54' and outsole 23, stopping short of the insole 20. A special h'eel for this purpose is illustrated in Figs.` -7 to 112 inclusive, and this heel comprises-a thin 'plate 46 of any desiredstiff material, but preferably of hard plastic such as a hard rubber. Thisplate is perforated and special pegs '48 also of 'any desired stiff material such as it, especially when the pad wears.

In the present case thirteen pegs are shown for fastening the heel, but more or less could be used. It is pointed out that where the holes are drilled and the pegs are forced into the holes, each peg is utilized to the same degree as all the others to obtain the holding efiect, so that the heelissecurelyiheld all the way around.. Where nails' or 'other driven fasteners which" make their own holes are used, they curl, bend, and other- ;wise become distorted so that very few of such jasteners actually hold anything, and in being clinched through the insole, nails form hard projections which injure or at least irritate the heel in 'the absence' of a pad. Even with a pad, the clinched nail ends will often raise humps through The-present invention provides a Construction wherein the heel is securely held to the shoe without the necessityof a heel padi and wherein theifa'steners .do nbteve'n `enter the insole as' a result of using* thel filler block as the holding medium. In this 'case the term plastic" is usedto refer to synthetic plastic'sjnatural rubber and artificial rubbers. v p i u -v "The same heeling .methodfabove'described is applicable to women'stop lifts'as shown in general at 60 in Fig. 12. 'The rubber lift is molded I, about a thin undercut hard plasticor rubber plate 62; the ?latter being provided with perforations for the ;receptioni of headed hard plastc or rubber pegs 64, ,and the' lift '60 is attached to the heel -by'first drilling the latter and then forcibly applying the combinedlift and pegs' thereto.

hard rubber or plastic are positioned in the per forations. The pegs are provided with broad .relatively flatheads 50- which are located on the side of the plate opposite a peripheral undercut 52. 4

When'the pegsand plate 'areassembledgthey i are placed in a'molding machine, and rubber forming the heel |6 is flowed around the. plate and pegheads ;and into the ,plate undercut and vulcanized ,to form a solid rubber heel. j

iWith the sole assembled as: inFig. 5, the outsole is appliedgand the last is placed ina heeling machine which is capable of exerting aghigh pressurejon the 'heel area of the =fi1ler 24 by means of an ,anvil or thelike. A heel'base* 54 may be adhe-sively applied to the filler, and a multiple drill is brought down to drill holes through the heel base, outsole,..and filler, but stopping short of the insole. 1 Material is removed to form the holes by drilling,.whereas punching the holes would result in spreading the base and outsole thus causing an uneven bulging at the edges of the s01e I-Ience the drilling does not have this effect and a more accurate fit of the heel base on theheel area is possible. Thevouter Plastic o hard rubber pegs 65 maybe used to fasten the heel itself to the insole.

, Having thus described my invention and the advantages thereof, Ido not wish to be limited to the details herein disclosed, otherwise than as set forth in'the claims, but what I claim is:

1. In a shoe; a sole Construction comprising an insole, a lip or the like attached to the insole and *following the'contour thereof, a relatively thicl;

filler block, secured to said lip and testing in fiat parallel relation ,on' 'said insole, said filler block being locatedsubstant'ally within the confines of said lip, an outsolelying over the filler block and lip, heel fasteners, saiduoutsole and filler i block being effectiveto ;receive said heel faster!.-

ers to-securea heel to the shoe, a heel held to said outsole and filler block by 'said fasteners, the latter extending through the outsole and penetratin'g thefiller block, .the outsole and filler block forming 'only receiving and; holding means edges of the :holes may be enlarged slightly to r a crtin Point where t omesysubstantia rigd and the forceis then,transmittedathrough thebroadpegheada r 1 for' the'heel fastene'rs in securing the heel to the solehzw u I '2.' In a shoe, a sole Construction comprising an insole, a lip 'on the 'insole following the contour thereof, 'a fillerblock thicker than the insole located in the heel 'area and 'within the lip and adapted to maintain the' same in' generally 'normal position with' respect to 'the insole, a line of stitching securing the filler block and lip together, an outsole lying over the fillerblock, the latter being thick' enough to receive and hold heel fastenersiin cooperation with the outsole, where bygsaid fasteners need not penetrate the insole, a heel,' fasteners extending from the heel 'through the efiller blockand outsole; 'said fasteners stopping short of the insole. i

e 3. A sole Construction asi recited in claim 2 wherein the filler block extendsfrdm the heel areaintotheshank area. '5 I emmm;
